SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Generate and organize product discovery thinking into an Opportunity Solution Tree that maps outcomes to opportunities, potential solutions, and experiments.

Core Features & Use Cases

  • Top-down outcome-first discovery: define measurable outcomes and align opportunities beneath them.
  • Multi-branch opportunity space: create multiple leaf opportunities with varied confidence levels and sources.
  • Solution options per opportunity: propose 2-3 concrete, scalable solutions with distinct scope.
  • Explicit assumption tests: attach riskiest assumptions and plan small experiments to validate them.
  • Rendered diagrams: output a Mermaid diagram for team communication.

Quick Start

Describe your desired outcome, and the skill will generate an OST with opportunities, solutions, and experiments.

FAQPage Schema
How do I create an opportunity solution tree for product discovery?

An opportunity solution tree connects a desired outcome to opportunities, solutions, and experiments. You define a measurable outcome, and the skill generates a hierarchical tree with multiple solution options and assumption tests for each leaf opportunity.

What is the best way to map product hypotheses to experiments visually?

Mapping product hypotheses to experiments involves attaching riskiest assumptions to leaf opportunities and planning small tests. The skill outputs a Mermaid diagram that visually renders these explicit hypothesis tests alongside potential solutions for team communication.

Can I generate multiple solution options for a single product opportunity?

Yes, you can generate multiple solution options for a single product opportunity. The skill proposes two to three concrete, scalable solutions with distinct scopes for each leaf opportunity within the hierarchical opportunity space.

How do I structure product discovery from a top-down outcome?

Structuring product discovery from a top-down outcome requires defining a measurable target, then aligning multiple leaf opportunities beneath it. The skill supports this workflow by generating a tree with varied confidence levels and sources for each branch.

Does this opportunity solution tree tool require any dependencies?

No dependencies are required to generate an opportunity solution tree. You simply describe your desired outcome, and the skill produces the full discovery structure with opportunities, solutions, experiments, and a rendered Mermaid diagram.

When should I use an opportunity solution tree instead of a flat product backlog?

Use an opportunity solution tree when you need to validate problems and design testable experiments in product discovery. It maps outcomes to opportunities and explicit assumption tests, providing a hierarchical structure that a flat backlog lacks for managing confidence levels.
